I do all of that, I've been around long enough to have learned. Like yourself. ps and tailing a daemon's log file is my standard approach to really verify that a daemon is running. The other side of the coin is I usually start with the distro's init scripts and assume for argument sake they work. When the facts prove that wrong, I dig deeper. The list of daemons I use that are not well behaved wrt init scripts are rather short in reality > If you're lucky, you've never had to start an unfamiliar service, or debug > someone else's unfamiliar config under time pressure... > Nope, not so lucky. Not even close. We're getting OT, but by far the worst behaved daemons out there are non-OSS paid-for things for a corproate market. Like Ossec. Oracle databases. Sybase. Anything and everythign that purports to do backups. I shan't mention Oracle's various offerings for business use for fear my brain shall explode. -- Alan McKinnon [email protected]
